I defined a class called Node as

private class Node {
      public Node father;
      public JigSaw js;
      public int dist;

      public Node(Node father, JigSaw js, int d){
        this.father = father;
        this.js  = js;
        this.dist = d;
      }
      public Node(Node aux){
        this(aux.father, aux.js, aux.dist);
      }
}

But, when I do

Node next_n = new Node(prev_n);

And change next_n contents, prev_n changes too! How can I get these objects unlinked?

Look up **deep** copy. – Hovercraft Full Of Eels Mar 24 '17 at 02:31
Helped. The trick was that the deep copy wasn't be done for JigSaw class! Not for Node. Thanks, – WithoutNameZin Mar 24 '17 at 02:59
No, the problem is that the deep copy was not being done for Node. Re-look at the answers. You need to copy deep within all children of the ultimate parent. – Hovercraft Full Of Eels Mar 24 '17 at 03:06
